I haven't attended one yet but I don't see it being viable for me, personally. The midwest area is going to have one of the largest potential RPTQs in the world seeing as they scheduled one RPQT relative for Illinois, Indiana and Michigan. With the potential of the event to be 200+ people, getting Top-8 in this event is still difficult but also denies a lot more spots for area players than before. I think this regional system is way better for smaller areas. If there were 28 players at a PPTQ in my area, I would ecstatic because that's a small turnout in my opinion. We get that many for GPTs for GPs that nobody is going to.
I don't have input on the participation of these tournaments but only on how they are structured and the potential implications they hold.
What do you think is the ceiling level on viable PPTQs? It seems like it would be insanely difficult to spike a 200 person PPTQ and then fly(on your own dime) to a PTQ with another 200 people and Top 8 that event. Though 28 people seems like a dream come true and might be easy to talk opponents into concessions (if they can't go to the big event).
